Research and Option in the Preparation of PVA-Alginate-Ca

Abstract:

Based on the index of water content, the influence of the dosage of glutaraldehyde, the mass ratio of polyvinyl alcohol(PVA) and alginate(NaAlg), the concentration of CaCl2, and the reaction time on PVA-alginate-Ca was discussed. It can be found that when the dosage of glutaraldehyde is 0.85%, the mass ration of PVA increases to 8:1, the solution quality score of CaCl2 is 2%, and the reaction time of PVA-alginate-Ca is 1.5h, the composite polymer water content reaches the highest.Then the preparation condition for PVA-alginate-Ca will be optimized by an orthogonal experiment design, and the optimum preparation condition will be found: ω (glutaraldehyde) is 0.85%, m（PVA）:m（NaAlg）is 8:1 andω(CaCl2)is 2.0%.
